#719-A Half-Tone Screen Determiner

This screen determiner is a more advanced version of the 719 and is designed for color work.
The front is just like the 719 but the back, (pictured), is used to determine the angle of each color.
The small dot in the center of the protractor determines the angle of each color as the color stars form when the grid is rotated to bring them in.
Amazing how it clearly separates each color except the yellow.
This item is also available for imprinting.
